The Oakland Athletics are are reportedly negotiating on two sites in Las Vegas as they step up plans for their seemingly impending move from California to Sin City - but could even remain in their current city.

According to Front Office Sports, the A's are assessing the Tropicana site and the Las Vegas Festival Grounds but would stay if a deal is struck on the long-running plans to build a $12billion stadium on the Oakland waterfront by Howard Terminal.

The Tropicana site in Vegas is owned by Bally's, which holds naming rights to Diamond Sports Group's 19 sports network that broadcasts Major League Baseball. 

The festival grounds, meanwhile, are owned by billionaire Phil Ruffin, who already has a hotel and casino in the area. 

The A's are in search of a new home as their current lease at the RingCentral Coliseum is going to expire in 2024.

An important deadline for finalizing an agreement in October over a $12bn waterfront stadium in Oakland was missed.

Furthermore, MLB commissioner Rob Manfred has said the team would have their relocation fee waived if they move to Las Vegas. It would have been in the region of $1billion.

'We’re past any reasonable timeline for the situation in Oakland to be resolved,” Manfred said in December.

And back in October, the San Francisco Chronicle also reported Manfred as saying: 'Given the situation in Oakland and given the fact that if you go to Vegas, you have to build a retractable-roof stadium, which adds about $500 million to the cost that a relocation fee (is) probably not appropriate.

'Time is running out. We can’t go five more years in the Coliseum,'
